To'aZZ whom it may concern: .I Be it known that l, Levi BROWN, of Rich- 'n1ond,' Indiana, have invented a new and useful mproveinent ain Wheel-Mountings, 'which invention is 'fully set torth 1n 4the' `tollowing specification.

The present invention is an improvement' This applicatlonis a division oi` applicanon ser-iai No. 622,992, med April 24, 1911.

f, j have cal rigidity betv1 'lt has heretofore been experienced in connectionfvwith lawn mowers, that-.the-.Severe usage to which machines of this Acharacter A-are subject has resulted in the loosening of vthe'' connectirms of the ground Wheels to the -slde frames, with the result that .said frames been subject to `increased strain and racking..

` `The improved mounting which forms the r`Subjestematter oi" the present invention so connects the ground Wheels to thev side 'rameefot the machine as to insure practieen these parts.

The invention will be better understood by reference. to the accompanying drawings which' illustrate one ernbodiment'otheinventive idea, and wherein, v

Figure l is a top plan view, partly in sec,- tion, o alawnmower providedwvithathe iinprowd mounting for ground `wheels; Fig. 2 is an enlarged sectional view, partly in eleyation, illustrating the means for rigidly the side gira-mes of 3 is an enlarged perspective view ot' the sleeve and cone member shown in section in Fig. 2.

Referring `to the drawings, 4, 4, indicate tivo side ranies ot the machine on which are mounted any suitable ground Wheels 5, stal tionaiy knife 6 and roller 7, said side frames v cated by l0.

being connected together by rod 8 -The shaft for the rotary cutter blades 9 1s indi As heretofore stated, the means for mounting the ground Wheels 5 of side frames i have for their primary object to effectively and rigidly connect the ground Wheels to said side frames. To this end a bolt 11., which is screw-threaded at one end, passes through each side trarne and is connected to the ground wheel by the'means hereafter den'iounftingva ground yWheel .to one v.ofi the machine 'and Eig.:

eine "ren bereide ateaeiieiwsich is providedwith` aadepiressiorr in which .a .suitadele'.v proyectiom 13.- on theside-frame e is adaptedto-engege to posttionfsaidbolt. A3

-c'one -l-f engagesfaround an enlargedpart of saidlboi-tvll, and the taperedace ot this cone lconstitutes the hearing1 surfaces' forthe balls 1.5 lcarried vin the ballholder 15. This cone is provided 'with -a plurality otrecesses 17, preferably.A diametricallyarrauged,fin which engage projections 1&3l prorideden a hollow sleeve 19. This hollow sleeveieprovided with internal screW-threadsQO.. and

external screw-threadsl. provided at. one. end thereof. A screvv-threaded conew engages the screw-threads 2.3i. on. said hollow sleeve, tandis-.provided With tapered surface which forms a bearing for the ball's'QB carried by the holder 24e Th-iseone member' 22 is provided with efpluraliigy4 of trensyerse perforations 1- 25 which are' adaptedto be brought-into alinement. withY a. slotti` ai ranged-in the end of bolt ll. and slots .-27 provided. in. the end otfhollowvy sleeve 19.,

vWhen theground-Wheel 5 is secured-to' the appropriate' side frame, 4, a. pin 28 is. passed throngzhthe perforation in .the .cone member 22 .Wh-iohdssin.-alinement with the slots in the bol-t.. a1id.hollow sleeve,.and thus the I- arts, are held ixedly inposition., l'nasseni ling these: artdthe bolt L11 is {irstpassed through ther sie e5 framedy and Ithe depression in the heads l2 -is engaged .with the-projection 13 onsaid side frame. The cone M is then slippedi' over 1 the bolt l1. vvand into the positionr'shown in Fig. '2, after which the hollow sleeve i9 is screwed onto the holt 11, the internal screw-threads 20 of said hollow sleeve engaging the screw-threads on said bolt. hen said sleeve has been screwed down so that the projections 18 thereon are in close pr Ximity to the recesses '17in the cone member l, said sleeve 1s sprung so that said projections 18 engage the recesses 5 is placed in the position shown in Figi,

' a iange'29-I carried by said Wheel engaging .the ball holder 16. This ange is provided '1 itis in proper position for the passing of the pin 28 through the alined slots in bolt 11 and sleeve 19, and one of the perforations 25 in said cone. When the parts are thus secured together, the ground Wheels will be rigidly and securely held to the side 'frames 4: and under all conditions of usage, it Will be found practically impossible to loosen the ground wheels 'from said side frames.

Any Wear of the wheel bearings that may occur during the life of the mower may be taken up by removing pinu 28 and tightening cone`22, and then passing pin 28 through slots 26 and 27 and the perforation in cone 22 which is in alinement therewith.

While the improved wheel mounting has `been lherein described with particular reference to lawn mowers, it will he understood that it may be used generally for the mountin of wheels. y

Vhat is claimed is:-

l. In a bearing, the combination of a frame, a rotary'el'ement, means for connecting said rotary element to said frame comprising a bolt, an element encircling said bolt and engaging said frame, a sleeve encircling sa-id bolt and engaging said element p vsaid sleeve and bolt having a screwthrea connection whereby rotation of said sleeve will tighten said bolt on said frame, and a bearing element encircling said sleeve.

2. In a wheelmounting, a frame, a rotary element, a bolt projecting through said frame, a sleeve engaging over said bolt, a second element engaging over said bolt, said sleeve and element being provided with connecting means and said sleeve and bolt beino provided with screw-threads whereby the rotation of said sleeve will tighten said sleeve and frame, said sleeve and bolt being provided with screw-threads whereby the rotation of said sleeve will tighten said bolt in position, a second cone provided on said sleeve and means for securing said bolt,

sleeve and cones in theirfixed position.

4. In a Wheel mounting,a frame, a rotary element, lboltVprojecting through said frame, means preventing the rotation of said bolt, a sleeve engaging overv sa'd bolt, a second element engaging'ove"\r 1s'l id bolt, said sleeve and elementbein provided with connecting lmeans and sai sleeve and 4bolt being provided with screw-threads whereby the rotation of said sleeve will tighten said bolt in position, and means' for securin said bolt, sleeve and element their. ixe position. y e

5. yIn a Wheel mounting, a frame, a rotar)7 element, a bolt projecting through said frame, a sleeve engaging over said bolt, a cone encircling said bolt and engaging said sleeve and frame, said sleeve and bolt being provided with screw-threads whereby the rotation of said sleeve will tighten said bolt in position, a cone adjustable on said sleeve, and means for securing said bolt, sleeve and cones in their fixed position.

In testimony` whereof I have signed this specification in the presence of twol subscribing Witnesses. A i LPN I BROWN.
